it will not change
there is no change
- sodium chloride is not an acid - in an acid solution the blue litmus paper become red
The Blue Litmus paper will turn into Red, while the Red litmus paper will retain its color. So it only indicates that the said mixture is an acid.
Hydrogen chloride gas is not an acid, is not in solution and does not donate protons. So, no litmus paper color change.
it will change to blue bcoz
there is no change
Sodium chloride water solution is neutral.
Sodium chloride solution is neutral.
The Blue Litmus paper will turn into Red, while the Red litmus paper will retain its color. So it only indicates that the said mixture is an acid.

Blue litmus turns red in acid. Sodium carbonate solution is alkaline (basic), so nothing will happen when blue litmus is put into this. Red litmus will turn blue if added to sodium carbonate.
The blue litmus paper will turn red. because the NH4Cl will form HCL (a strong acid) and NH3 (a weak base).
Hydrogen chloride gas is not an acid, is not in solution and does not donate protons. So, no litmus paper color change.
Litmus paper doesn't "do anything" to a solution. Litmus paper has some dyes on it, so some of the dyes might leak into the solution though. NaCl won't do anything to Litmus paper either. Salt, when dissolved in water, maintains a neutral solution. Litmus paper only changes color when there is a pH change. So, nothing really will happen.
it will change to blue bcoz
a)sulfur dioxide b)hydrogen chloride c)potassium sulfate d)slaked lime
The litmus papers are used for checking the acidic and basic nature of any substance. That's why drop of lemon juice, which is by nature acidic, turns blue litmus into red(as the property of acidic solution is to change the color of blue litmus to red). So soap solution which is by nature basic will turn red litmus into blue (as the property of basic solution is to change the color of red litmus to blue).
